Createing a Windows Store (tile) installer

I am able to build Windows 8.1 Store apps in VS 2013 that can detect multiple touches.

What I need to do is regularly send updated versions of the app to someone who has a Lenovo Horizon All-in-one PC with multi-touch and running Windows 8.1.

My question is how to I turn my VS project into an installer I can send to them? Rather than going via Windows Store.

Thanks in advanced.

If it’s suitable for you to send Visual Studio solution, than you can use MSBuild to build install app.
Otherwise PowerShell probably is the only option.
